I have not seen anything related to this at bugzilla.lyx.org:
Put the cursor at the end of your doc. Start spellchecking. Then click on
stop spellchecking, move the cursor to the beginning of the file, and click
on start spellchecking. Lyx crashes with:
lyx: SIGSEGV signal caught
Sorry, you have found a bug in LyX. Please read the bug-reporting
instructions in Help->Introduction and send us a bug report, if necessary.
Thanks !
lyx: Attempting to save document /home/mw/Karcsi_bacsi/diffu.lyx as...
/home/mw/Karcsi_bacsi/diffu.lyx.emergency
Save seems successful. Phew.
I have
$ rpm -q lyx
lyx-1.2.1-2mdk
I'll file a better report if this is unknown.
